Simplifying m2 + 4m + -25 = 0 Reorder the terms: -25 + 4m + m2 = 0 Solving -25 + 4m + m2 = 0 Solving for variable 'm'. Begin completing the square. Move the constant term to the right: Add '25' to each side of the equation. -25 + 4m + 25 + m2 = 0 + 25 Reorder the terms: -25 + 25 + 4m + m2 = 0 + 25 Combine like terms: -25 + 25 = 0 0 + 4m + m2 = 0 + 25 4m + m2 = 0 + 25 Combine like terms: 0 + 25 = 25 4m + m2 = 25 The m term is 4m. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4m + 4 + m2 = 25 + 4 Reorder the terms: 4 + 4m + m2 = 25 + 4 Combine like terms: 25 + 4 = 29 4 + 4m + m2 = 29 Factor a perfect square on the left side: (m + 2)(m + 2) = 29 Calculate the square root of the right side: 5.385164807 Break this problem into two subproblems by setting (m + 2) equal to 5.385164807 and -5.385164807.Subproblem 1
m + 2 = 5.385164807 Simplifying m + 2 = 5.385164807 Reorder the terms: 2 + m = 5.385164807 Solving 2 + m = 5.385164807 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + m = 5.385164807 + -2 Combine like terms: 2 + -2 = 0 0 + m = 5.385164807 + -2 m = 5.385164807 + -2 Combine like terms: 5.385164807 + -2 = 3.385164807 m = 3.385164807 Simplifying m = 3.385164807Subproblem 2
m + 2 = -5.385164807 Simplifying m + 2 = -5.385164807 Reorder the terms: 2 + m = -5.385164807 Solving 2 + m = -5.385164807 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + m = -5.385164807 + -2 Combine like terms: 2 + -2 = 0 0 + m = -5.385164807 + -2 m = -5.385164807 + -2 Combine like terms: -5.385164807 + -2 = -7.385164807 m = -7.385164807 Simplifying m = -7.385164807Solution
